class BlobsRepository

Bases: Repository[Blob]

Type

alias of Blob

count_orphans()

async create(values, /, *, session)

Parameters:

values (dict | Blob)

delete_orphans()

select_orphans()

The ids delete_orphans would remove.

Deleting blobs with a bulk statement leaves anything caching their existence, such as SqlBlobStorage.seen, believing rows are there that are not. The caller needs to know which ids went, so the count, the selection and the deletion all read from one definition of “orphan” and cannot drift apart.
